The answer is C
C has units of Markers / Markers on the left and Money over an unknown which represents money.
None of the others (D) is incorrect, because we've already chosen C.
A is not because.you have the wrong amount of money divided by the larger number of makers.
B does not work because the right is markers divided by money. The left had side will have money divided by markers. It won't work. The safest way to these questions up is to keep the knows on the left and put the unknown on the left with the number it is associated with.
Let's see why the others don't work.
You have to multiply by a -1 both sides,
it would be 10 1/2
Volume = 1/3 pi r^2 h
= 1/3 * 10^2 *81 pi
= 2700 pi units^3
Its C
< ABC is a straight angle
no right angles
no complimentary angles
< ABD and < DBC are supplementary angles
Answer:
x = 12
Step-by-step explanation:
Pythagorean triplet
12,16,20
So, the value of x is 12
x + 256 = 400
